Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk-type automatic continuously variable transmission.

[0002]

2. Description of the Related Art A conventional transmission has a clutch device.
Alternatively, a change system (multi-stage) using a number of gears is provided by adding a device utilizing the viscosity of oil.

[0003]

In the conventional transmission, there is a disadvantage that a rotational shock (shattering shock in the rotational change) occurs in a change in rotational speed.
Although the number of stages is increased in order to compensate for this, the number of mechanical parts increases proportionately, which has been a further disadvantage.
In the present invention, the contact rotating part (5) is moved in contact with the disk (4) to cause a stepless rotation change utilizing the difference in the circumferential distance of the disk (4), and the number of mechanical parts is large. There is no. Thus, an object of the present invention is to eliminate the disadvantages of the conventional transmission.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention makes it possible to produce a smooth variable speed rotation by utilizing the difference in the circumferential distance of the contact surface of the disk (4). . Details will be described with reference to the drawings. B) The contact rotating part (5) is moved along the rotating surface of the disk (4). Depending on the moving state, the circumferential distance of the contact disk changes, resulting in a continuously variable transmission. The maximum gear ratio is the diameter c (11) / the diameter d (12) of the disk (4). (Πc / π
d) (FIGS. 1 and 2) b) In the case of the movable power source (1), the contact rotating part (5) moves with respect to the disk (4) in the case of the movable power source (1) and the rotating shaft of the power source ( 6) and the contact rotating part (5) are integrally formed within a horizontal distance (9) from the center of the disk (4) to the outer periphery.
(FIG. 1) In the case of the fixed power source (2), the power source rotating shaft (6) and the contact rotating part (5) are integrated into the disk (4) within the change angle (10) from the center to the outer periphery. Do. (Fig. 2)
For the movable power source (1) and the fixed power source (2), 0
A description will be given of a 006 embodiment. C) The moving operation of the contact rotating unit (5) is automatically controlled by the ratio between the rotation speed of the power source shaft (3) and the rotation speed of the power source (1, 2) and the resistance ratio of the power source (1, 2). Or manual control. D) The contact rotating section (5) includes a power source rotating shaft (6) coming from the power sources (1, 2), and a contact rotating body a (7) and a contact rotating body b (8). E) If the case where the contact rotating body a (7) is connected to the power source rotating shaft (6) is defined as forward rotation (FIG. 3), the contact rotating body a
By removing (7) and connecting the contact rotating body b (8), the operation becomes reverse rotation (FIG. 4). Also, the contact rotating body a (7)
The rotation of the power source (1, 2) and the power source shaft (3) are removed by removing the rotating body b (8) from the power source rotating shaft (6).
Rotation becomes irrelevant. (FIG. 5) Each rotating body a
B (7, 8) is independently connected to the power source rotating shaft (6), and the connected rotating body a (7) or b (8) comes into contact with the disk (4).

[0005]

According to the combination of the above-described devices, the rotation of the power sources (1, 2) is controlled by the forward rotation through the contact rotating body a (7) and the reverse rotation through the contact rotating body b (8). The rotation is transmitted to the source shaft (3). In addition, a smooth stepless speed change can be performed by the contact movement within the horizontal distance (9) or the change angle (10) during rotation.

【Example】

B) In the case of a movable power source (1) (where the position of the power source is movable, such as a motor that can be easily moved)
It takes the form of the general view (FIG. 1). B) In the case of a fixed power source (2) (a fixed power source / a gasoline engine or the like that cannot be easily moved), the configuration shown in FIG. 2 is adopted. C) The rotation of the power source (1, 2) is based on the power source rotation shaft (6).
Through the contact rotating part (5), and the contact rotating body a (7)
Rotates the disk (4) to produce a forward rotation of the driven source (3). D) The rotation of the power source (1, 2) is based on the rotation of the power source rotating shaft (6).
Through the contact rotating part (5), and the contact rotating body b (8)
Rotates the disk (4) to produce the reverse rotation of the driven source (3). E) With the disk (4) and the connecting rotating part (5) connected, in the case of the movable power source (1), the movable power source (1), the power source rotating shaft (6) and the contact rotating part (5) are integrated. In the case of the fixed power source (2), the power source rotating shaft (6) and the contact rotating part (5) are integrated to change the angle (10).
, A continuously variable transmission is performed. F) When both the contact rotating body a (7) and the contact rotating body b (8) are not connected to the disk (4), the power source (1, 2)
The rotation or stop of the power source rotating shaft (6) does not affect the disk (4) and the driven source shaft (3). G) In the case of a chopper-type motor (a motor that can be used for both a motor and a generator) as the power source (1, 2), the disk (4) is used by utilizing the rotational inertia of the driven source shaft (3). By connecting the contact rotating part (5), the power source (1,
It can also be used for power generation in 2) and braking (control) of the driven source shaft (3). (H) In order to reduce the rotation loss in the contact between the disk (4) and the contact rotating part (5), the power source rotating shaft (6) and the contact rotating part (5) are synchronously moved. I) The power sources (for movable (1) and fixed (2)) can be used not only by direct connection (FIGS. 1 and 2) but also by other rotary connecting devices. D) When reverse rotation is not required as a whole device, parts and operations relating to the contact rotating body b (8) can be eliminated, and the number of parts can be reduced.

[0007]

The present invention has a great feature that it can be used for all power sources (movable (1), fixed (2)) and that there is no rotational shock in variable speed rotation. Further, forward rotation and reverse rotation can be easily performed in connection, as well as in rotation (idle rotation) independent of both such as rotation of only the power source (1, 2) and rotation of only the power source shaft (3). Can be used.
